So the issue isn't the epoxy/PVC interface, but the PLA itself? Yes even printing at 100% it's not going to be as solid as you think it's just the nature of 3D printing. Materials like Ian mentioned such as PETG may have claims of being waterproof but I believe its only refereed to as waterproof wh...

I've tried this SEE HERE and it didn't work. I also make a lot of 3D Printed fishing lures and I full coat them with epoxy and I've still had pin holes that can fill the lure up even at 8-10 feet of depth... when they get back to the surface they are like a squirt gun. You can try it but I highly re...

Thanks,

I'm actually hoping to get back into this in the next week or two... so hopefully I'll have some progress to post.

Looking good... I'm glad to see someone getting use out of those kort nozzles I designed.

This post reminds me it's about time I dig my Rov out of the closet and get around to finishing it too.

You could do that but it would make for a heavy and stiff tether plus you would need other wires for the lights, camera, ect. I can up with this basic system seen in this post (http://www.homebuiltrovs.com/rovforum/viewtopic.php?f=15&t=1592) It allows you to use one pair of wires for power and t...

There are a ton of different CAD programs out there these days such as Solidworks, Onshape, Fusion360, Bender, ect. If your just getting started in CAD I would suggest Fusion360. It's free and there are a lot of tutorials on Youtube that will help you get started.

Very cool I just might have to give that a try... I'll bet there are some 3D printed ones out there already too.

Thanks... The end caps on the camera tube were machined from a solid rod of PVC. This was the stuff I used https://www.mcmaster.com/catalog/125/3738 (PVC Rods 2") Any hard plastic should work though. I tested the 3D printed parts out and yeah unfortunately even at 100% infill they will not work...

The issue was the thruster cables had water ingestion going through the sheathing and into the WTC. This was an issue I expected at greater depths, but not < 20 ft! I did come up with a potting solution for the cables that did fix this, more info on that in an upcoming post. Yeah that does happen.....
